does suspension? Not exactly what you're asking there... the only way to guarantee you don't damage your subframe is to remove your rear swaybar all together and never get a new one. That, of course, would be lame, so the better option would be to use a reinforcement kit. Brian, the "inventor" and seller of the bsq kit claims he has never heard of a tearout with his kit (which costs like $20). There is documentation on the internet of at least one person tearing their subframe with the beaks kit installed (although who knows if it was installed properly). But either way, we're talking one in tens of thousands.
